Two new 2'-oxygenated flavones, 5,2',6'-trihydroxy-7-methoxyflavone (3) and skullcapflavone I 2'-O-beta-D-(4"-E-cinnamyl) glucopyranoside (5), together with three known flavones, 7-O-methylwogonin (1), skullcapflavone I (2) and skullcapflavone I 2'-O-beta-D-glucopyranoside (4) were isolated from the whole plant of Andrographis elongata, and the structures were elucidated by FAB-MS and one- and two-dimensional (1D- and 2D)-NMR spectral studies including 1H-1H correlation spectroscopy (COSY), heteronuclear single quantum coherence (HSQC), heteronuclear multiple bond connectivity (HMBC) and rotating frame Overhauser enhancement spectroscopy (ROESY) experiments, and chemical studies.

The antipyretic activity of a herbal formulation, TBR-002 was compared with that of andrographis paniculata, andrographis elongate and paracetamol in yeast-induced pyrexia in male albino rats, TBR-oo2 was found to be effective at an oral dose of 100 mg/kg in the inhibition if pyrexia. Its efficacy was almost comparable to that of paracetamol as well as andrographis elongate, the antipyretic activity of andrographis paniculata, the well known antipyretic herb, was found to be less than that of the above drugs.
